The S roll is scratched and the water cooling squeezing effect is not good. The water is brought into the S roll. The difference between the furnace body tension and the outlet looper tension is too large, which constitutes the S roll slipping.

In the process of application of color coated rolls, we can't avoid some small achievements, which we must face. The following is a detailed list of the results that will appear.

First, the detailed parts of the color coating roll:

1. Substrate scratch

2. When making veneers, pay attention to the scratches on the back, and the color difference will occur. The light color on the back is easy to occur

3. Scratches on the spray pipe: mainly refers to the front of the strip

4. Scratches on the guide plate at the entrance section (main back)

5. Scratches in curing furnace The objects inside the curing furnace are sagging (rare), and the front side is scratched due to excessive tension. Most of them refer to excessive tension when thick materials are replaced with thin materials.

6. Scratches on the exit loop during emergency stop and parking unloading (rare)

7. Scratches on the squeeze roll. Usually, when the extruding roll does not rotate

8. The foreign matters at the outlet section are scratched, and there are foreign matters on the outlet guide plate, and most of them are on the back or the scissors

9. The S roll is scratched and the water cooling squeezing effect is not good. The water is brought into the S roll. The difference between the furnace body tension and the outlet looper tension is too large, which constitutes the S roll slipping.

10. The temperature of the curing furnace plate for initial coating is not enough, and the paint is not cured well. The back paint is stuck off by the shaking roller before water cooling

The steel raw material market is stable. The market is stable in the later period.

Pig iron market prices have not changed, demand is still not good, poor transactions, manufacturers inventory differences. It is understood that there is still no substantial improvement in downstream demand. Downstream steel mills are cautious about purchasing pig iron for steelmaking. Some steel mills temporarily stop external procurement.

Film Forming Mechanism of Color Coated Steel Coil

Non transformative. Generally, it refers to the physical film forming method, that is, it mainly depends on the volatilization of solvent or other dispersion medium in the film, and the film viscosity gradually increases to form a solid film. For example: acrylic paint, chlorinated rubber paint, ethylene paint, etc.

How to distinguish the quality of color coated steel coil

Observe the edge leakage of the color steel plate: when taking the color steel plate, observe whether there are fine, gray, black and impurity crystals in the exposed steel plate, such as the section. If the cutting surface is crystal clear, the quality will be better.

Storage time and inspection items of galvanized steel coil

If it is stored for a long time, it is recommended to simply check and clean it every week. If there is a certain amount of dust accumulation, it should be cleaned in time. In addition, problems such as deformation and collision should be handled in time.

Classification and process of galvanized coil

Alloy, composite galvanized coil This is an alloy made of zinc and other metals such as lead, zinc, etc. It is even a composite steel plate galvanized pipe steel plate not only has excellent rust resistance, but also has good coating performance.
